and crank shaft bearings of a well pumping mechanism.

Another object of the invention is to provide a novel type of walking beam specially designed to'be mounted on said walking beam bearing.

A further vide, in device of the character described, a novel type of bracket employed.

lV ith the above and other objects in View this invention has particular relation to certain novel features of construction, arrangement of parte and use. :tu-example of which is given in this specification and illustrated in the accompanying drawings, wherein z- Figure 1 shows a fragmentary side eleva tion of a pumping" apparatus, embodyingmy invention.

Figure 2 shows a fragmentary front" elevation thereof.

Figure 3 showsa plan view of a type of walking beam employed, an d Figure i shows a side view thereof.

Referring new more particularly to the drawings, wherein like numerals of reference designa-te similar parts in each of the figures the numeral 1 designates a foundation, preferably of concrete. Upstanding from this foundation there is a post 2. preferably consisting of a section of pipe. rlhis post 2 rests on a foot B, which is anchored in place by a rod 4t whose lower end is embedded in the foundation and whose upper end is fitted through a central bearing' in the foot 3.

Mounted on the upper end of the post 2 there is a yoke 5 having` the upstanding spaced bearings 6, G, in which the respective ends f the bearing rod 7 work and a walking beam S is mounted on said rod. The post 2 is braced by the brace rods 9. 9, 9, arranged in tripod fashion a n d preferably tubular in forni. The voke has the downwardly diverging studs 10. whose lower ends are reduced to fit within the adjacent ends of the brace rods 9. The lower ends of these brace rods rest on the brackets, as 11, mounted on the foundation 1. Each bracket 11 is secured to its foundation by means of anchor bolts, as 12, the lower ends of said anchor bolts being embedded in the foundation 1 andtheir upper ends being fitted through the corresponding bracket and featureof the invention isto pro-l outwardly tthreaded to receive nuts, as 13. Each bracket'` 11 has a hook 14, formed thercon, having a sloping y'face y15 'against which the lowerend ofthek cor-responding rod 9 rests and there are tie rods 16, 16, 16, formed with eyes at their lower ends, which engage over the hooksfll and whose upper ends arek y also formed with eyes'which engage ,throughk eyes, as 17 carried by the yoke 5. These tie rods are equipped with turn buckles,ras18, by means of which they may be loosened `or tightened up tosecure the ro`ds9, iirmlyibetween ther studs 10, at theirupper ends, and the bearing faces 15, at their lower ends. Adjactmt-the lower end of the post 2 there is a hook 19, setin the fondation 1, and the post 2 has an eye 20 anda ytiey rod 21 connects said hook 19 and yeye 20said tie rod 21 ybeing equipped with a turnbuckle 22. Beyond the hook 1a each bracket llvhas an inwardlyy fac-k ing hearingface 23` having afgreater pitch, or inclination than the pitch of the rface 15 and. this bearing face 23, has a boss 24 thereon.

Upstandingfrom the foundation 1 thcrciis another post 25,`similar to the post 2',y but` preferably shorter and ymounted on a foot 26, secured to the fondation in a manner similar to the foot 3.

On the top of this post 25 there is a bearing plate 27 formed with a half bearing 28 and a bearing cap 29 is secured on said plate to complete the bearing 8O in which the crank shaft 31 works. On opposite sides of the post 25 there are the hooks 82, 32. which are embedded in the foundation 1, and anchor rods 33, are engaged with the hooks 32, at their lower ends. and their upper ends are fitted through the plate 27 and threaded.r to receive the ynuts Sli. The plate 27 has the downwardly diverging bosses. as 35, and tubular brace rods, as 36, have their upper ends fitted over said bosses with their lower ends fitting against the respective bearing faces 23 and receiving the bosses 24, of the corresponding' brackets 11. Suitable tie rods, as 8T, are connected to the plate 27, at their upper ends and their lower ends are formed with eyes which engage over the respective hooks 1a of the corresponding brackets 11 and these tie rods 37 have the turn buckles 3S by means of which they may be lengthened or shortened. The crank shaft 31 has a suitable crank arm y89 connected at one end to the pitman 10, which in turn is connected to the corresponding' end of the walking beam 8. The other end of this I of` walking beam employed.

ybeam is connected to the pump rod (not shown) inrany conventional manner.4

The bra'ce rodsV 9 and 36,'are preferably formed of sections, united by means of suitable couplings, as 4l, and said brace rods may be vlengthened, or shortenedby adding a section or detaching one, as desired.

Lnection toal pitrnan at one end and to a pump -rod'at the other.

nested vin the yoke 43 andV is secured therein.'

The bar 41 isseated or by means of the clamps 44 whichit over said bar and have iianges 46 which coincide with,k the flanges 45 of'sai'd yoke and the clamp `bolts 44 pass through the coinciding flanges 45, 46, carried byfsaid yoke and platesV respectively. The walking beam has a transyverse bearing 47 provided to receive the usual A `bearing rod as 7. Ad]acent each end of theV 30 walking beam there'are the collars48 secured thereon, each collarihaving lateral Veyes 49 and connecting these eyes'49, on each side,

j are the guy rods 50 which pass over an upstanding central post 5l ymounted on the bar 4l'and these guy rods v50 are equipped'with seat, a bar having vertical end slots and resting in said seat, clamp plates fitted over the bar, said yole and plates having coinciding flanges, clamp bolts through said flanges securingsaid bar to said yoke, a collar. adjacent each end of the bar, each collar having f lateral eyes, an upstanding central post mounted on said bar, guy rods passing over the upper end of said post and whose respective endsy are connected to the 'corresponding eyes. f

2. In a'device of the character described, a Walking beam including a yol-:e having a lengthwise groove, orminga seat, a bar resting in said seat, spaced clamp plates tted overV said bar, said plate and yoke having coinciding flanges, clamp bolts through said flanges securing said bar to said yoke, a col- .lar secured on said bar adjacent each en-d thereof, each collar having lateral eyes, an upstanding central detachable post mounted onV said bar between Vsaidfplates, guy vrods passing over the upper end of said post and whose respective ends are connected to the corresponding eyes, and a turn buckle incorporated into each guy rod.

. In testimony whereof I have signed my name to this specication.
